Thruflow decking

Does anyone have experience with this stuff?
How does it feel on bare feet?
Does it truly work against wave action?

Buddy of mine had it done on his dock. Feels ok but very rigid. A good hurricane will take anything you put. The deck is only good as what it’s attached to.

The more open space the less likely it will come up during a flood for sure. Looking at all the options including $$$ I think I am just going with treated southern yellow pine in 5/4 deck boards. It's as hard as a lot of hardwoods and its orders of magnitude cheaper than some of these specialty dock materials.
I am looking at 600 sf of dock plus some decking around my boat under the covered area so when some of those products are $15+ per sf it gets expensive quick. I am splurging on the best pilings and hardware I can get, the stuff above water can be replaced if I don't like it much easier down the road.

This is the way for us normal folk.

But here’s what has happened to me several times
Storm comes in, brings high water and strong wave action. It covers my entire dock by several feet.
During the hours of water, debris and wave action, the boards, which want to float but they’re screw down so they behave as a frictional force and start to wobble and once fhe water recedes, the dock and pier are all cockeyed with some or all missing boards.
The longer the storm, the worse it gets.
With one dock I had, i purposely had the deck boards nailed down with short nails- not screws. It was a sacrifice to the water action. After one storm the boards blew off and piers were okay. Another storm, some boards came off. Some of the pier was cockeyed tho.
With thruflow, they tell me it works 2 main ways- no bouyancy and no /less friction on water. The water flows through. I have only seen one example personally and it worked but I don’t know what storm it went through.
So I understand the concept, seen one example personally.
I’m fairly convinced on the stuff but I really like to have more real world examples.

The best I have seen that holds up to flooding is fiberglass grating. No buoyancy, very minimal flow resistance, and comes in giant sheets that can be attached with stainless strapping. A friend's pier in grand isle has been like that for at least 15 years now and hasnt had to be redone yet. Its not very barefoot friendly though, very spartan stuff. Also very good at allowing dropped things to go into the canal.

I'm on a canal on the north shore, it doesn't really get wave action. My dock has been underwater once since we have been living here and that was one of the storms last year that blew the water in just right.
If the storm is bad enough to damage my pilings too, the dock is the least of my worries. The current dock is in bad shape only because of previous owner syndrome. They used screws that are just rusting away and didn't properly bolt any headers to the pilings. They really used all 8-10ft boards and screwed them into the pilings instead of proper galvanized threaded rod and hardware. I think a properly built dock with SYP will be fine for my location and budget, and if/when I decide to upgrade I would be dealing with a late teenage son who is looking at driving and post secondary education, I am sure that will free up a ton of disposable income .
